OH CRAP...sorry guys.................................and thread started -_______-...I read the original post real quickly, and I didn't read very carefully...
what I meant to say was that the new 2006 ///M Coupe/Roadster's rims will fit non-M E46's...I'm not sure about any other wheel <=[ sorry, my mistake...

as for the main issue...it's never going to possible to fit other ///M rims onto non-M, due to the offset. ///M offsets tend to be too severe for non-M's unless you roll the fenders (wheel well lips) or maybe get a wide-body kit o_O!...the only set that I know will fit is like I said above ^^^ [new M coupe/roadster rims --> non-M E46]
